Protection part for the electronic circuit of a survey meter, and high range gamma-ray survey meter having same inserted therein

摘要

Provided is a protection part for an electronic circuit of a survey meter and a high range gamma-ray survey meter into which the protection part is inserted, in which the protection part is easily mounted in the survey meter to prevent the electronic circuit from being short-circuited when a conductive material is introduced into the electronic circuit. The protection part includes an insulator part for interrupting electricity other than that used for a signal transmission cable, an elastic stainless steel sheet part inserted into the insulator part, and a cable hole part through which the signal transmission cable passes when the protection part is inserted into the high range gamma-ray survey meter. Also, the protection part is inserted into the high range gamma-ray survey meter such that a telescopic part hole and a display part of the high range gamma-ray survey meter are physically separated from each other.

主权项

1. A protection part for an electronic circuit of a survey meter comprising:
an insulator part for interrupting electricity other than that for a signal transmission cable of the survey meter; an elastic stainless steel sheet part formed of a typical elastic stainless steel sheet and connecting the insulator part and a cable fixture of the survey meter; and a cable hole part through which the signal transmission cable passes when the protection part for the electronic circuit is inserted into the high range gamma-ray survey meter.
